I use Gold Tip 5575 and 75gr Rocket Mini-blaster 3s. I shoot a Legacy at 65lbs and 285 fps I shot a deer at 15 yards It went in just behind the shoulder and double lunged it. The broad head nicked a rib going in and went right through a rib going out and stuck in the ground on the other side, the deer went about 35 yards. My dad has killed a lot of deer with his 57gr rockets.
